Auto-Setup: When using a Parker motor and the Aries Support Tool, this
command is automatically set for the selected motor.
If you did not use the Aries Support Tool, are using non-Parker motors, or
sent an RFS command to the drive, the parameter is set to zero (0)—you
must manually set this parameter to a non-zero number. Otherwise, the drive
reports the configuration errors E1–Motor Configuration Error and
E6–Resistance = Ø, and shuts down the drive.
For a list of automatically configured commands, see DMTR.
The DMTRES command sets the motor winding resistance. This resistance
value is measured at 25°C at the drive end of the motor cable (motor cable
included). This resistance is the phase-to-phase resistance measured at
terminals U to V, V to W, or W to U.
Warning — Disconnect the motor cable from the drive before attempting to
make this measurement. For best accuracy, and to avoid injury, this
measurement must be made with the motor cable disconnected from the
drive.
